Two Different Sacraments

Baptism is the introductory boundary of the church. Communion is the continuing or exiting boundary of the church. Some say 1 Corinthians 11:27 brings negativity, but maybe that's what Paul was trying to get at. What makes a sacrament? Baptism is a converting ordinance, the supper is not. Baptism is passive, the supper is active. They both should not be done outside official churches. Paul talks about examining yourself, but he means in the context of the community. Some argue that the body is the church, not the flesh of Christ.
